I think this is just a clock issue. Pings include timestamps and sequence numbers, and /proc/sys/net/ipv4/icmp_ratelimit does as the name suggests.
On the domU guest, echo 1 > /proc/sys/xen/independent_wallclock Do the live migration Then echo 0 > /proc/sys/xen/independent_wallclock I bet your clock and ping issues will both be resolved. Not yet tested (by me): does setting independent_wallclock on the dom0's do anything? That would be nice, because then you wouldn't have to take the time to ssh to guests before live migrates. (Anyone else have a good workaround? Is there any way to give user-space a hint that the kernel is starting a live migrate?) Frequently suggested but not desired (by me): use independent_wallclock all the time, and run NTP in each domU. -- Rich Graves http://claimid.com/rcgraves Carleton.edu Sr UNIX and Security Admin CMC135: 507-646-7079 Cell: 952-292-6529 _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
